CAR-TRUCK- Specification of Letters Patent.

Application filed February 6, 1905. Serial No. 2%,495-

To all whom, it may concern.-

Be it known that I, WILLLAM P, BET'rnnDoRr, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Oar-Trucks, of which the followingis a full, clear, and exact description.

My invention relates to car-trucks having cast-metal side frames; and its object is to permit the attachment to the ends thereof of the Master Oar-Builders standard journal-boxes with the least expenditure of labor and the simplest mechanism possible and to combine with these novel features a spring-mounted roller-bearing swing-bolster. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings, Figure 1 is a side view of a oar-truck embodying my invention, showing the journal-box at one end thereof and open and at the other end removed. Fig.

2 is a plan view of one-half of said truck. Fig. 3 is a vertical transverse section taken on dotted line 3 3, Fig. 1. Fig. 4 is a side elevation of the broken-away central portion of a modified form of side frame, showing a bolster-opening therein, the lower portion of which is wider than the upper portion, to which modification my improvements are applicable. Fig. 5 is an enlarged detail view, partly in section, of the end of the upper arch-bar and its supporting-column and showing the means for retaining the journal-box.

Referring to the drawings, A A represent the axles of car-wheels, the journals of which have hearings in the journal-boxes B, which latter are of the type known as the Master Oar- Builders standard journal-boxes, and comprise a cast-iron box or case which incloses the journal of a car-axle, the journal-bearing, and key, and which holds the packing forlubricating the journal. Thesejournal-boxes are provided withlaterally-projecting lugs a a and 7) Z) on each side thereof, down through which it is the practice to insert suitable bolts, whose ends extend through the end extensions of the tie-bar and the arches of the'side frame.

My invention avoids the use of the bolts nearest the center of the side frame, together with the nuts and cotters that go with it, as hereinafter more fully appears, and diminishes the amount of labor and time required to insert or remove said journal-boxes from the ends of the side frames just one-half.

The side frames of my invention are cast in one piece of metal and comprise an upper arch O, a lower arch D, column-guides E E. a horizontal arm 0, projecting from each end of the upper arch, and a lower horizontal arm d, extending from each end of the lower arch of the side frame. The ends of the upper and lower arch are connected by vertical columns F F, and the edges of these end columns, against which the journal-boxes come in contact, are provided with laterally projecting flanges e, which at their upper and lower ends are provided with boxes f f, each of which latter have recesses or sockets f therein for the reception of the lugs b b of the journal-boxes. All of the outer edges of the side frames, as well as the edges of the openings therein, are flanged laterally to strengthen the frame and improve its appearance, and the arms 0 (Z form oontinuations of the upper and lower flanged edges of said side frames. In order to reinforce and improve the appearance of these arms 0 cl, they are provided with longitudinal central ribs 0' d, respectively, the projection of the rib 0 of the upper arm 0 preferably being greater than the rib of the lower arm in view of the greater strain thereon. These arms extend the same distance from the ends of the side frame and are provided with vertical openings g near their outer extremities, down through which the bolts G extend. When the journal-boxes are inserted in place between said arms, so that the lugs I) 6 thereof enter the sockets in the boxes f f, said journal-boxes can be securely attached to the ends of the side frame by tightening up said bolt by means of a suitable nut h and cotter j.

The sill of the bolster-opening is preferably provided with flanges H, that project farther on either side of the side frame than elsewhere, and at their centers of width (or at a point coinciding with the vertical plane of the web of the side frame) these flanges are provided with a longitudinal groove k. A spring-plank Iconnects these side frames, and its end portions (from which the downward side flanges possessed by the remainder of its length are omitted) lap over and rest upon the flanged sill of the bolster-opening and are provided on their under side with a transverse tenon m, which enters and engages the grooves 76.

The bolster-springs J J rest, preferably, directly upon the ends of the spring-plank and by keeping the tenons m thereof in the groove in the sill of the bolster-opening hold said plank in place and securely connect'said'side frame together. Resting on and supported by springs J is acap K, the upper surface of. which is provided, as shown, with parallel transverse concavities an, in each of whicha bearing-roller 0 0 is placed. The ends of the truck-bolster N, which extend intothe bolster-openings of the side frames, rest on these rollers, and the under side of the'said .ends are provided withsuitable plates O,-that have parallel transverse concavitiesintheir under surfaces which are engaged by said rollers, the same as in similar types ofswingbolstertrucks.

The swing of the bolster is limited by suitable guide-lugs q q, secured to and projecting from the sides of the bolster adjacent to the inner flanged edges of the guide-columns, and by a suitable transversely-disposed stop-lug Q, secured to the top of the bolster N. This disposition of the devices forlimiting the movement of the bolster permits the-side frames, when the springs have been removed from under the ends of the bolster andthe bolster lowered sufficient to enable the lug Qitmpass through the bolster-opening and the journalbearing and wedge removed from the journals of the axles so that the collars thereof will not prevent the removal of the axles from the journal-boxes, and the spring-plank and such brake-beam as the truck may possess removed, to be moved laterally outward off of the bolster and the parts of the truck separated. Cast in one piece with and projecting horizontally inward from the side frames, adjacent to the upper ends of the guide-columns and on each side of the bolster-opening, are studs R R, which are preferably tubular and have the inner portions of the bore thereof-reduced to form seats for pins from which the brakebeams are suspended.
